1 . A spout for filling containers with a liquid, the spout comprising a body defining a liquid feed duct and having a bottom terminal portion in which there extend firstly a plurality of dispenser channels in communication with the feed duct and secondly an exhaust channel in communication with a vent of the filler spout, the dispenser channels having a flow section that is smaller than the flow section of the feed duct. 
     
     
         2 . A spout according to  claim 1 , wherein an exhaust valve member is mounted in a portion of the exhaust channel extending in register with the dispenser channels so as to be movable relative to a seat between a low position in which the valve member is separated from the seat in order to open the exhaust channel, and a high position in which the exhaust valve member presses against the seat in order to close the exhaust channel. 
     
     
         3 . A spout according to  claim 1 , including a primary dispenser valve member movably mounted in the feed duct in register with a seat to control the dispensing of liquid, and a secondary dispenser valve member mounted in register with an internal transverse wall of the body to be movable between a first position in which the secondary valve member bears against the internal transverse wall and a second position in which the secondary valve member is separated from the internal transverse wall, the dispenser channels opening out in the internal transverse wall in such a manner that the secondary valve member in the closed position closes the dispenser channels, in particular so as to prevent them emptying, the spout including means for controlling the secondary valve member synchronously with the primary valve member. 
     
     
         4 . A spout according to  claim 3 , wherein the control means comprise an actuator rod connecting together the two dispenser valve members. 
     
     
         5 . A spout according to  claim 1 , wherein the bottom terminal portion is fastened under a main portion of the body by removable fastener means. 
     
     
         6 .
